In figure: installation seat plate 1, balance bent plate counterweight end 2, balance bent plate contact site 3, bearing block 4, bearing 5, axle 6, balance bent plate 7, balance bent plate guide end 8, godet roller 9, limit body 10, connection 11, microswitch 12, arc-shaped limit hole 13, normally opened contact driving chip 14, balancing weight 15, holding screw 16, adjusting screw(rod) 17, yarn 18.
The specific embodiment
In Fig. 1 ~ 3, a kind of for judging the whether checkout gear of fracture of wire of yarn, comprise installation seat plate 1, it is characterized in that: the middle part of balance bent plate 7 is hinged by axle 6 and installation seat plate 1, axle 6 is bearing on bearing block 4 by bearing 5, bearing block 4 is fixedly connected with installation seat plate 1, and the balance bent plate guide end 8 of balance bent plate 7 is provided with godet roller 9, and the balance bent plate counterweight end 2 of balance bent plate 7 is provided with balancing weight 15;
A side at balance bent plate counterweight end 2 is also provided with microswitch 12, and the normally opened contact driving chip 14 of microswitch 12 contacts with the balance bent plate contact site 3 of balance bent plate counterweight end 2;
Described balance bent plate contact site 3 is positioned at a side relative with balancing weight 15.Structure thus, when the bifilar straight sth. made by twisting of fine denier filament, during disconnected one yarn, the balance of balance bent plate 7 can lose, thereby pushes down the normally opened contact driving chip 14 of microswitch 12, by connection 11, sends signal, by program judgement yarn fracture of wire.The utility model adopts the mode of balance bent plate 7, the small tension variations that acts on godet roller 9 can be detected, when tension variations occurs breaking one yarn, whole mechanism is disequilibrium, thereby raising accuracy of detection, the test problems of disconnected one yarn while solving bifilar straight sth. made by twisting of fine denier filament.
Preferred scheme in Fig. 1 ~ 3, is provided with the arc-shaped limit hole 13 for spacing balance bent plate 7 rotational angles on installation seat plate 1;
Described balance bent plate 7 is through arc-shaped limit hole 13; This example adopts this structure, rotational angle that can limiting balance bent plate 7, α as shown in Figure 3.
In another optional scheme, or the bar being fixedly connected with described balance bent plate 7 is through arc-shaped limit hole 13.Structure, also can realize the effect of the rotational angle of limiting balance bent plate 7, so be also feasible, not shown thus.
In Fig. 2,3, in a side of balance bent plate guide end 8, be also provided with limit body 10.The limit body 10 arranging is the rotational angle of limiting balance bent plate guide end 8 further.As the position of the C in Fig. 2,3, C '.
In Fig. 2,3, described balancing weight 15 is connected with balance bent plate counterweight end 2 by adjusting screw(rod) 17.Structure, is convenient to regulate the position of balancing weight 15 thus, thereby adjusts the tension force to yarn.
In optional step, described balancing weight 15 is provided with internal thread, forms threaded engagement with adjusting screw(rod) 17.Structure, is adjusted at the position on adjusting screw(rod) 17 by rotating the mode of balancing weight 15 thus.
In Fig. 2,3, described balancing weight 15 is provided with through hole, forms and is slidably matched with the outer surface of adjusting screw(rod) 17 smooth section, and direction vertical with adjusting screw(rod) 17 axis on balancing weight 15 is also provided with holding screw 16.Structure thus, by unclamping or fastening adjustment screw rod 17 is adjusted the position of balancing weight 15 on adjusting screw(rod) 17.
During normal operating conditions, if yarn tension is a definite value, yarn makes balance bent plate 7 in C position by godet roller 9, now balancing weight 15 gravity are less than or equal to yarn to the moment of axle 6 and act on pulling force on the godet roller moment to axle 6, and 3 pairs of normally opened contact driving chips 14 of balance bent plate contact site are without pressure, and normally opened contact driving chip 14 freely flicks, microswitch is in normally open, now microswitch 12 disconnects, no signal output, and machinery is normally worked.
When yarn disconnected one or two bursts, yarn tension reduces, and the pulling force that now yarn acts on godet roller will be less than the moment of balancing weight 15 gravity to axle 6 to the moment of axle 6, and balance bent plate 7 pendulum angle α are to C ' position.Now, balance bent plate contact site 3 drives driving chip 14 actions, microswitch 12 closures, and signal passes to control centre by holding wire 11, by program judgement yarn fracture of wire, thereby mechanical single ingot is stopped, and reaches the function of broken yarn self-stop.
When twist yarn fiber number difference or technique difference, only need to unclamp holding screw 16, regulate the position of balancing weight 15 on adjusting screw(rod) 17, can make its Yarn twisting that is adapted to each tension section, accurately judge yarn fracture of wire problem.
The test problems of disconnected one yarn when application of the present utility model has solved bifilar straight sth. made by twisting of fine denier filament.
